The human knee is still well ahead of what even the most advanced human engineers have managed.
Miller and Luskin discuss fruit flies, finch beaks, stickleback fish, mutational hotspots, phenotypic plasticity, and the gravity well model.
A diagram in the paper — showing interactions in terms of engineering schematics — is unlike any description of the flagellum that I’ve seen.
What do biologists make of the apparently purposive nature of all these different kinds of complex programmed behaviors?
Dean Schulz investigated the design of the flagellum with a method that could be described as groundbreaking.
